Ad libitum [116K]3 years ago
6 0
True, that is a document that is left to a person over 18 years old, who may be a family member or not, that person may be able to make decisions for the patient if he or she loses the ability to make decisions for themselves. When designating a healthcare agent, you can make sure that the medical professionals respect the patient´s wishes. The agent can also decide how wishes can be applied as the illness changes. Hospitals, doctors and others medical professionals must follow the decisions of the health agent if they were the patient´s

Which of the following is NOT a part of an ATP molecule? Select one: a. adenine b. ribose c. chlorophyll d. phosphate
Gnesinka [82]

Answer:

C (Chlorophyll)

Explanation:

Adenosine triphosphate (ATP) is an energy carrying molecule in all living cells. It is the usable form of energy by cells. Organisms are able to carry out cellular functions using the energy carried by ATP molecules. ATP like other molecules is made up of components that make up its chemical structure.

ATP is composed of three structural components; A five-carbon sugar called RIBOSE at the core of its structure, attached to a nitrogenous base called Adenine and phosphate group (three in ATP). The energy in ATP is released when it loses its phosphate component.

Chlorophyll is a pigment found in the Chloroplast of plant cells. It is another molecule that is made up of its own components e.g nitrogen, magnesium etc.

What is an example of a relationship between organisms in which an organism produces energy that is used by another organism to
agasfer [191]

Answer:

Tree frogs use plants as protection. Golden jackals, once they have been expelled from a pack, will trail a tiger to feed on the remains of its kills. Goby fish live on other sea animals, changing color to blend in with the host, thus gaining protection from predators.

If a mutation causes a permanent change in the DNA sequence, how is it that most mutations are “silent” mutations?
IgorLugansk [536]

Answer:

(look at the explanation below)

Explanation:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Does the size of the particles change as a substance changes state
Kazeer [188]
Ok, particle is not a very nice word, no real sense of size associated with it
it can be a group of molecules like a speck of sand
referring to the molecules themselves
or refering to the atoms that make up the molecule

now in terms of phase change,
if we consider a speck- a group of molecules- then solids will expand when heated, however this definition falls flat in terms of phase change

ok, how about molecules, as molecules undergo phase change, the molecules in relation to each other will move apart from one another. Solid- molecules are bonded, Liquids- molecules are close and flow around each other, Gas- molecules are a significant distance from one another. But the increase in size when you heat up a molecule, i would have to say yes. adding heat increases energy which increases molecular vibration which would probably  increase the overall average size to some unnoticeable degree.

now standalone atoms are just atoms, if you want to consider the electron cloud as size, then heating it up would negligibly cause the outer move outward. but it really depends on the scale of the question
